Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position information notification system for notifying various position information corresponding to a position by using position information obtained by a mobile communication terminal, and in particular, to a position information notification system used in this system. The present invention relates to a technology for realizing efficient operation in an information notification server and a mobile communication terminal.

[0002]

2. Description of the Related Art As is well known, a mobile telephone system based on the PHS (Personal Handy Phone System) has a function of identifying position information of each terminal.
In addition, even in a mobile phone system, it is becoming possible to acquire position information of each terminal by using a GPS (global positioning system).

Conventionally, various position information notification systems using such position information of mobile communication terminals have been constructed. For example, there are a system that manages the current position of a taxi at a center to efficiently dispatch vehicles, and a system that provides information on stores existing near the user's current position.

A problem in such a position information notification system is how to set the timing for updating the content information to be notified with the movement of the user. That is, since the user does not know how much the content information will change, it is necessary for the terminal to access the server periodically or every time the user moves a certain distance. On the other hand, the server must respond to the access request even when the position of the terminal is not out of the management area and the content information to be notified does not change.

[0005] In view of the above, there has been studied a method in which the mobile communication terminal efficiently notifies the center server of the current location. For example, a method in which the range in which the terminal moves is divided into a plurality of regions in advance, and the terminal notifies the server of the current position when the terminal moves from the current region to another adjacent region, or the server transmits the region information to the terminal. There has been proposed a method of notifying a server of a current position when a terminal goes out of the area.

However, in the above-mentioned prior art, the terminal must previously have information on the area and program information for determining whether or not the server is out of the notified area. For this reason, there is a problem that it is difficult to change the information of the area and the judgment program.

[0007] In particular, since a terminal can use only a specific server corresponding to the area information and program information held therein, a system that uses a plurality of servers, each of which manages an area by a different method, is constructed. In such a case, the terminal must have the area information and the judgment program information corresponding to each server, and there is a problem that the load on the terminal increases.

[0008]

As described above, in the conventional position information notification system, the condition (for example, area information such as area) for notifying the current position in advance on the mobile communication terminal side.
There is a problem that it is difficult to change the condition and the condition determination information because it is necessary to have the condition determination information such as a program for determining the condition and the condition. In addition, there is a problem that the terminal can use only the specific server corresponding to the condition and the condition determination information held therein, and cannot use the server that manages the condition by a different method.

Therefore, the present invention solves the above-mentioned problem, and efficiently notifies the current position even if the mobile communication terminal does not have a condition or condition determination information for notifying the current position in advance.
An object of the present invention is to provide a position information notification system capable of receiving desired content information, and a position information notification server and a mobile communication terminal capable of realizing the system.

[0026]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a system diagram showing a configuration of an embodiment of a position information notification system according to the present invention. This system is a store information notification service system that provides information (content information) of stores existing near the current position of the user in a push type. That is, a mobile communication terminal (hereinafter, referred to as a client terminal) C owned by a user is automatically transmitted to a location information notification server (hereinafter, referred to as an information providing server) S via a network N such as a public network, regardless of user operation. The server S searches the information database D based on the notified current position, finds information on stores existing near the position, and transmits the information to the client terminal C. is there.

In the above-described system configuration, the client terminal C includes a position acquisition unit activation unit PGK and a position acquisition unit P
G, a position information notification unit PN, a condition determination unit CJ, an information reception unit IR, and an information display unit IV. Information providing server S
Includes a position information receiving unit PR, an information searching unit IR, a condition determining unit CD, a condition determining unit managing unit CJM, and an information transmitting unit IS.

Hereinafter, the information contents of the information database D, and the respective functional units in the information providing server S and the client terminal C will be described in order.

First, the information contents of the information database D will be described.

Store information is stored in the information database D in advance. The store information also includes information on the position of the store. The location information can be in any form. For example, the name of the nearest station, latitude and longitude information, and the like can be considered. FIG. 2 shows an example of the store information storage format when the information on the location of the store is the nearest station name, and FIG. 3 shows an example of the store information storage format when the information is the latitude and longitude information.

When information is stored using the name of the nearest station, a table relating to the location of the station is also prepared. This table manages station position information and information on a range in which the station is the nearest station. This position information may be in any format. For example, latitude and longitude information, P
An HS base station ID can be considered. In the example of FIG. 2, latitude / longitude information is stored.

The range information may be of any format as long as it is the minimum necessary information for specifying the range. For example, if the range is represented by a circle, the latitude and longitude information of the center point and the radius of the circle are considered.If the range is represented by a rectangle, the latitude and longitude information of each vertex is considered.If the range is represented by a polygon, vector information connecting the vertices is considered. Can be In addition, the base station ID of the PHS included in the range may be considered. In the example of FIG.
The range is represented by a circle, and the latitude and longitude information of the center point and the information of the radius of the circle are stored.

Next, each functional unit of the information providing server S will be described.

The position information receiving section PR has a function of receiving the position information of the client terminal C notified by the client terminal C. The location information may be in any format. For example, latitude / longitude information, PHS base station I
D and the like are conceivable.

The information retrieval section IR has a function of retrieving information from the information database D, and retrieves a store near the position of the client terminal C received by the position information receiving section PR.

For example, when store information is stored in the information database D in the format shown in FIG. 2 and the current position of the client terminal C is represented by latitude and longitude information, first, the location information of each station in the station information table is used. , Client terminal C
Calculate the distance from to each station and determine the nearest station. Next, a store whose nearest station matches the nearest station of the client terminal C is extracted from the store information table.

When store information is stored in the information database D in the format of FIG. 3, the distance from the client terminal C to each store is calculated.
Of stores located within a certain distance from the current position of the client terminal C and the stores near the current position of the client terminal C are extracted.

The condition determining unit CD has a function of determining a condition for the client terminal C to notify the next position information.
Hereinafter, the content of the condition determination will be described using a specific example.

First, when store information is stored in the information database D in the format shown in FIG. 2, even if the client terminal C repeats the notification of the position information at the position where the nearest station is the same, the information search unit IR performs the search. There is no change in store information. Such a location notification increases communication volume unnecessarily,
The load on the information providing server S will also increase.

In this case, the notification may be made when the nearest station is out of the same range. Therefore, the condition determining unit C
D is a condition for acquiring the range information of the nearest station of the client terminal C obtained by the information search unit IR from the information database D, and as a condition for notifying that the user goes out of the range represented by this information. In addition, the station information table of FIG. 2 may be used to manage information of an adjacent range, and a condition for notifying that the user enters a range represented by the information of the adjacent range may be considered.

Store information is stored in the information database D in the format shown in FIG. 3, and information on stores located within a certain distance from the current position of the client terminal C or a certain number of stores from the closest one is stored in the client terminal C. The same problem as described above arises in the case where the above is provided. That is, if the distance between the existing locations of the stores is large with respect to the interval for acquiring the current location and the moving speed of the client terminal C, even if the location information is notified each time the location is acquired, the information search is performed. There is no change in the store information searched by the department IR, the communication amount is increased wastefully, and the load on the server is also increased.

Therefore, when the information search section IR searches for a store located within a certain distance from the current position of the client terminal C, for example, as shown in FIG. It checks the shortest distance from the current position of the client terminal C, obtains a value obtained by subtracting the above-mentioned constant distance from the distance, and notifies that the distance is greater than or equal to the distance obtained from the point where the current position was first notified. Condition.

When the information search unit IR searches for a certain number of stores from the one closest to the current position of the client terminal C, for example, as shown in FIG. Is determined as a condition for notifying that the user is more than the calculated distance from the notified point.

FIGS. 4 and 5 each require a range in which it is not necessary to notify the user. In addition to such a condition determination method, it is conceivable to determine the conditions in consideration of the moving speed and the moving direction of the client terminal C.

The condition judging means management section CJM has a function of managing information relating to means for the client terminal C to make a condition judgment. This information can be in any form. For example, a calculation formula, a program for actually performing a determination process, and the like can be considered.

The means for making the condition determination largely depends on the format of the store location information stored in the information database D. When store information is stored in the format of FIG. 2, the distance between two points is obtained from the latitude and longitude information of the client and the latitude and longitude information of the center point of the circle given as the range information. It is a calculation formula or the like for checking whether or not it is longer than the radius of the circle given as the range information.

The information transmitting section IS has a function of transmitting information to the client terminal C. This information includes the store information searched by the information search unit IR, the information on the condition that the client terminal C should notify the position information next determined by the condition determination unit CD, and the condition determination unit management unit CJM. Information about the means managed by the client terminal C for making a condition judgment is included.

Next, each functional unit of the client terminal C will be described.

The position acquisition section activation section PGK includes a position acquisition section P
It has a function to start G. Any method can be used to determine the activation. For example, there are a method of starting at a fixed time interval and a method of starting when a certain condition is satisfied.

The position acquisition unit PG has a function of acquiring the current position of the client terminal. The means for acquiring the position information may be any means. For example, there is a method of acquiring latitude and longitude information using GPS, and a method of acquiring a PHS base station ID.

The position information notification unit PN has a function of transmitting the position information acquired by the position acquisition unit PG to the information providing server S.

The condition judging unit CJ judges whether to notify the position information based on the condition specified by the information providing server S by using the condition judging means specified by the information providing server S. have. The conditions specified by the information providing server S and the condition determining means are obtained from the information receiving unit IR.

The information receiving section IR has a function of receiving information transmitted from the information providing server S. This information includes:
Store information, information on a condition to be notified of position information next, and information on means for making a condition determination are included. The store information is passed to the information display section IV, and the condition and condition determination means are passed to the condition determination section CJ.

The information display section IV has a function of displaying the shop information notified from the information providing server S in a format that is easy for the user to see. This store information is acquired from the information receiving unit IR.

In the system shown in FIG. 1, the processing flow when the client terminal C receives the information providing service will be described below. Here, in the client terminal C,
It is assumed that the position acquisition start unit PGK starts the position acquisition unit PG at regular time intervals from when the service starts to be received.

The client terminal C side (1) Upon receiving an instruction to receive an information service by a user's operation, the position acquisition activating unit PGK activates the position acquiring unit PGK.
Start

(2) The position acquisition unit PG acquires information on the current position of the client terminal C and passes it to the position information notification unit PN.

(3) The location information notifying unit PN accesses the information providing server S and transmits the location information acquired in (2).

(4) The position information receiving unit PR receives the position information in response to the access from the client terminal C, and the information search unit IR
Pass to.

(5) The information search unit IR searches the information database D for information on stores existing near the current position of the client terminal C based on the position information obtained in (4), and condition the search result. The information is passed to the decision unit CD and the information transmission unit IS. Subsequently, the condition determination unit CD determines a condition for the client terminal C to notify position information next based on the search result, and passes the determined condition to the condition determination unit management unit CJM and the information transmission unit IS. . The condition determination means management unit CJM passes information on means for the client terminal C to determine the determined condition to the information transmission unit IS.

(6) The information transmitting unit IS transmits to the client terminal C the store information and the conditions acquired in (5) and the information on the means for the client terminal C to make the condition judgment.

The client terminal C side (7) The information receiving section IR receives the shop information, conditions, and condition judgment means transmitted from the information providing server S, passes the shop information to the information display section IV, and judges the conditions and conditions. The means is passed to the condition judgment unit CJ.

(8) The information display section IV displays shop information.

(9) The position acquisition activating unit PGK activates the position acquiring unit PG a fixed time after the last time the position acquiring unit PG was activated.

(10) The position acquisition unit PG acquires information on the current position of the client terminal C, passes it to the position information notification unit PN, and calls the condition determination unit CJ.

(11) The condition judging unit CJ judges whether to notify the position information based on the condition given by the server S and the condition judging means. If the condition judging unit CJ judges to notify, the process from (3) onward is repeated. If it is determined not to notify, (9)
The subsequent processing is repeated.

As described above, the server S dynamically specifies the condition for notifying the client terminal C of the position information, so that the client terminal C notifies the server S of only the position information useful for the server S. Becomes possible. As a result, the amount of communication for location information notification is reduced,
The load on the server S can be reduced. The server S also provides a means for performing a condition determination, so that the client terminal S can flexibly respond to a change in data format. As shown in FIG. 6, a plurality of servers SA (determination information: latitude / longitude of a center point of a circle) And radial distance, determination means: f (x, y)), SB
(Judgment information: latitude / longitude of rectangular vertex, judgment means: g (x, y)
), SC (judgment information: set of vectors, judgment means: h
(x, y)), ... can also be used.

In the above embodiment, the information database D stores the position information in a format based on the latitude and longitude information as shown in FIG. 2, while the position information notified from the client terminal C is stored in the base station. In the case of the ID, the server S needs to obtain the latitude and longitude information from the base station ID.

As a method for realizing this, there is a method of creating a table for managing the ID of the base station and the latitude / longitude information of the location as shown in FIG. When the information search unit IR of the server S receives the information of the base station ID notified by the client from the position information reception unit PR, the information search unit IR acquires the latitude and longitude information of the corresponding base station using the table of FIG. The store information is searched using the information in the same manner as in the above embodiment.

The information providing server S provides the information to the client terminal C.

As a method for realizing this, there is a method of managing the station information table of FIG. 2 as well as range information using the base station ID as shown in FIG. In addition, a method of dynamically obtaining the ID of the base station included in the range shown in FIG. 2 using the range information of the station information table of FIG. 2 and the base station information of FIG. 7 can be considered.

As described above, the server S changes the format of the condition for notifying the position information according to the format of the position information notified by the client terminal C, thereby allowing the client terminal C to obtain the position information. Instead, the client terminal C can notify the server S of only the position information that is useful for the server S, so that the communication amount for notifying the position information can be reduced and the load on the server S can be reduced.

In the above embodiment, the data format stored in the information database D is unified in the table, and the information providing server that is frequently connected while the client terminal C is receiving the service is not changed. In this case, it is not necessary for the information providing server S to transmit information on the condition determination every time a response to the position information notification from the client terminal C is made.

Therefore, as shown in FIG. 9, a condition judging means request section CJS is added to the client terminal C shown in FIG. 1, and a condition judging means answering section CJR is added to the information providing server S.

The condition determining means request unit CJS of the client terminal C has a function of requesting the information providing server S to provide a means for determining the position information notification condition, and receiving the determining means as a response. When requesting the provision, the information provision server S also passes information necessary for selecting the determination means.
